Topic: [Guide] Dogie's Comprehensive ASICMiner Blade Setup - page 59. (Read 580775 times)

Hi guys,
Blades have 2 pin female connectors for fans. I have only 3-pin Arctic Cooling F12 fans. How to connect these to 2 pins? On eBay I only found 1 auction in USA (I am in Europe) to adapters like this one: http://www.ebay.co.uk/itm/YAD2P-3pin-to-2pin-converter-adapter-/270681240944?pt=US_Computer_Case_Fans&hash=item3f05dbf570#shId
Any other idea (or link to Europe shop with parts) how to make them working nicely without cutting wires?

Thanks, I will give this a try when I get home!

You can have multiple instances of stratum proxies running on the same computer. The default getwork listening port is 8332, but only 1 instance can use that port. The second instance must use a different port, and this can be specified using the -gp option.

Edit: Oh yeah. The stratum proxy also listens on port 3333 for stratum clients, although blade users don't care about this. For multiple instances, you also need to set this to something different (use the -sp option) to avoid an error message. I usually use "-gp 18332 -sp 13333" for the second instance, "-gp 28332 -sp 23333" for the third instance, etc.

Guys,  how do I set up my backup pool to use stratum?

The first one is easy.  I have stratum proxy running on my computer.  But if I want my backup pool to also use stratum, would I enter the same ip and just have a separate instance of stratum that is running all the time, not doing anything until the first pool fails?  Or would itbe better to have it running on a different computer, and thus a different ip in case there is some kind of "interference"?  I am afraid to test this until I get some guidance lol... Every second of mining counts especially with the difficulty hike coming up.  :/

Only testing to see if that works. I put both btcguild stratum servers so if the first one goes down it should connect to the second one.

Hey all..

First of all thanks to dogie for this wonderful guide and numerous suggestions through PM's discussing the config of the components. You can see that i have incorporated several components from the OP of the guide.

However, the mounting case was my idea.. Here are the pics of my setup. I have only 2 blades.. so i planned my mounting stand for only 2.
Probably, i can accommodate another 2 blades if i change the orientation of the existing blades.

I used the Hutten wine rack from IKEA. http://www.ikea.com/us/en/catalog/products/70032451/
I chose this because, (1) It was cheap (2) I can mount another rack on top of this or along side this.
Made some modifications to the original rack. Please note that the height from the top panel to the bottom panel is about 0.75 inches shorter than the height of the blade. So the pre-drilled holes by IKEA will not work. You will have to either drill new holes or use nails instead. I simply used nails.

Secondly, i took off the round wooden dowels from the center section.
Apart from that, I used a few metal corner brackets, screws, nuts and bolts.

Image 1 : Front View : 6 channel fan controller, Netgear Switch, CX 750M and 1 Blade with 2 x 120 mm fans (push - pull) on the heatsink.



Image 2 : Side view : Here you can see blades and 2 fans at the bottom. The fans on the heat sinks are fixed to the frame using the corner brackets and the blade is fixed to the fan using the cable ties. It is pretty rock solid and firm. No vibration or noise of any kind.

Image 5 : View of the complete setup. Apart from the 6 X 120 mm fans, i have a Honeywell HT-900 table fan blowing from the side to keep the entire system cool.

With an year average of 44,000,000 difficulty, a 12GH/s blade is on track to return 50 BTC over that year.

If the year/average goes above 44M... then it will take longer.  Based on Avalon miner and chip sales, Asic Miners farm expansion plans, I expect the difficulty to hit about 40M in October/November (~6 months).

At this pace, how much time do you think we'll need to reach the break-even of our beloved blade(s)? Have you made any calculations?

Does the proxy support multiple getwork hosts at once? And how it manage them (switch, etc.)?

All:

This is the beginning of my day 2 of full mining with 2 blades on btc guild.
Since a few hours ago I have begun to use a proxy for the stratum servers and got higher speed and efficiency. Here are the results right from my btc guild dashboard:

Totals (All Active Workers)   25,912.97 MH/s  ... (99.83%)

Pretty good!

On my 1st 24 hours I got 1.12 BTCs +change. I may do better in this current period with the above speeds. One little thing that seems to improve performance with the proxy is to run it in the background (linux) with the output going to /dev/null instead of in the foreground going to the screen.

Here's my proxy command and notice I do not use user/password in the command so I can use only one proxy for 2 or more blades, each configured with its worker username and password:

nohup python mining_proxy.py -o stratum.btcguild.com -gp 8332 -o eu-stratum.btcguild.com -gp 8332 > /dev/null 2>&1 &

This is my pick for the winner config that gives me the speed above.

Cheers.

Port is 8332

so if i want to connect 50btc.com i should use below command
cd C:\Program Files (x86)\Stratum Proxy
mining_proxy.exe -o pool.50btc.com -p 3333
but it does not work....something wrong?

Trust me, that is cable managed. If you look from above there is a core of cabling surrounding the upper bar, and nothing outside the profile of the fan blocks.



Switch has none but is cold, doesnt need any. The larger fan controller might get a fan if I can be bothered, the tiny heatsinks inside are dissipating a decent amount of heat. I have 3x140mm fans I was going to use to help draw the heat up, just testing without at the moment.

What's interesting is the bottom push fans are ramming alot of the heat down. I've adjusted the top pull fans up to see how it affects things.

Awesome Dogie.. good one..looks good.
may be a little cable management will increase the air flow and ventilation i guess.!

Otherwise looks good.! So do you have any fan or airflow for the switch and fan controller.. piling them together on top of the PSU might get them little ehated up.

Also what is the temps that you are getting on the power modules.
The power module on one of my blade is hotter as compared to the other blade.. The same board has one "X" as well.
Probably i should test the volts of the power lane.

Anyway, am getting the stuff that i ordered for my mounting case today.. probably will post the pics over the weekend.

Created my 6th mounting system. Most of the parts didn't arrive so had to ghetto mod. Only single rail at the top [was going to do 2], all the corners are actually tee's xD No cable ties of the right side so shit load of wire ties.




4 fans per blade, bottom two in push, top two in pull.

Blades mounted vertically so heatsink naturally convects


12 fan controller


Another 8 fan controllers and an 8 port network switch
Only 3 connections required - mains power for the PSU, mains power for the network switch and a single ethernet cable to router.

Window sill mountage

Stealth mode engaged [aka cleaner invisibility cloak]

Printing monies

Move the mining_proxy.exe into a folder called "Stratum Proxy" in your program files x86. Create a text file on the desktop. Enter the following and then save it as a .bat.

cd C:\Program Files (x86)\Stratum Proxy
mining_proxy.exe -o eu-stratum.btcguild.com -p 3333

It will then open cmd and start the proxy with the custom settings. You can also set it to be silent (in the background) or to be a windows service.

     How do I start? Can you explain? Proxy by default on slush. Many say eg.:
- BTC Guild the raw command will be : mining_proxy_1.2.0.exe -o stratum.btcguild.com -p 3333
- 50BTC the raw command will be :     mining_proxy_1.2.0.exe -o pool.50btc.com -p 3333.
   But how, where, what?

You need to download, install and then run it with the help flag.

where is the this documentation?thanks
